Hi Mr. Bunce,
I am a developer recently using Perl on one of my projects. I got a DBI
question but couldn't find solution by searching the web. I'll greatly
appreciate if you could help me out.
I am trying to port a C code into Perl using your DBI module. The C code
uses ODBC API SQLBindParameter like below:
nRetVal = SQLBindParameter( m_hstmt, 1,
SQL_PARAM_INPUT, SQL_C_WCHAR, SQL_WVARCHAR,
15, 0,
Col2Values[nIndex] , 15, &lParameterSize);
The 4th and 5th parameter value type SQL_C_WCHAR, SQL_WVARCHAR must be
passed to the driver for Unicode support. However, your DBI module
bind_param function only provides 3 interfaces:
$rc = $sth->bind_param($p_num, $bind_value);
$rc = $sth->bind_param($p_num, $bind_value, $bind_type);
$rc = $sth->bind_param($p_num, $bind_value, \%attr);
I tried the 3rd interface, but I don't know what attributes the \%attr
expects. In ODBC.pm, I only saw attributes are NAME, NULLABLE, TYPE,
PRECISION and SCALE.
Would you please advise how can I use bind_param call in DBI to get the
equivalent of the above C code.
Thank you in advance for your help,
